 | ArePackageCabsEmbedded | Always set to false to keep the .cab files external to the .msi files. This save user disk space: Burn caches packages so it can always uninstall and repair. MSI also caches packages for uninstall. If the cab is embedded, you have two copies and MSI doesn't always use its cached copy as a source for repair. With an external .cab, MSI caches only the tiny .msi file and not the (relatively huge) .cab. |
